Good price for those on prime. I think it might be £8.99 in Argos at the minute (half price) for those without prime. Seems to have good reviews.

The Mobile Med Kit combines two popular ways to play. Toddlers can press the siren on the ambulance to launch medical missions, then race over to help patients with medical tools on hand. Or they can play with the four included tools-a stethoscope, otoscope, thermometer and syringe, to role play giving and getting checkups at the doctor. Designed by LeapFrog experts for children ages 2 years and up, the Mobile Med Kit tickles funny bones while nurturing learning. Rolling the ambulance and pressing the siren prompts songs, such as "Head, Shoulders, Knees and Toes," as well as fun phrases that teach about health and hygiene. Kids can practice using the stethoscope like a doctor, and pretend to hear a heartbeat. They can twist the thermometer to see who has a fever, check an earache and give the all clear with the purple otoscope, and hear the syringe squeak as they practice giving a vaccine. Friendly sound effects help prepare children for real medical checkups with role-play fun.
